INTRODUCTION: During the 1st wave of CoViD-19 pandemic there was a drastic reduction in total number of accesses, with more serious cases and a exorbitant increase in crowding, due to access block. OBJECTIVES: evaluate population who went to ED for (1) mental disorders requesting a psychiatric visit and for (2) intossication and substance abuse, between the first and second wave of the coronavirus pandemic METHODS: We enrolled all patients who went at our ED from May 1 to October 20, 2020 and during the same period of 2019. We analized: vital parameters, age, sex, exit severity codes, hospitalization rate, Crowding input factors (number of access, waiting time, priority time to doc), Crowding throughput factors (LOS: Length Of ED Stay), Crowding output factors (percentage of access block; Total Access Block Time). RESULTS: The results are shown in table 1 [Table: see text] CONCLUSIONS: We would like to thank all employees of the IRCCS Policlinico San Matteo Foundation for their extraordinary efforts during the pandemic.
